I'm still deciding which way I want to go with the U87....VINTAGE or Ai. I thought I would see if anyone had any tips if I was to go with the vintage u87 is there anything in particular I should check or watch out for ?

Check the diaphragm. Some of the older ones are a little flaky looking due to moisture and spittle.I had mine (75) modded by Ross Giles in Melbourne to remove the top end rolloff that Neumann put in due to not being able to interfere radio pilot tone. Sounds great, but as I say the diaphragm is worth checking, I've seen some where the gold sputtering is wrinkly or even missing in spots.

Ours we got from the US and as it turns out it sports a completely new replacement body, an Ai body I guess. Inside it's an i model with the battery compartment and all, but Neumann couldn't tell me much more than that, the number on the bottom of the mic head wasn't something they kept records of either.Still not sure how I feel about all of that... Might have to get it checked for the capsule now too...

I heard someone mention they'd sent their mic to Neumann for repair and it come back a different colour, with the body sleeve replaced. They considered it too denty I guess, hehe.

They made the old ones until 1986 apparently, batteries are available on eBay.

I used the original ones for 10 years amongst 2 u47 and 4 u67 We always used the 87 before the 67 but the 47 first on vocals I dont remember them being special

Them I bought a u87 ai which was my only mic for a while before i learnt how to find old neumanns It was incredable but it suffered from loose tension so it was super sensitive and blew out And shut down on loud sources , i have now seen a number like that Great great mics but faulty And recently i had a u67 like that same magic but shut down on loud sources so actually faulty I correct working u67 and u 87 of any kind never sounded so good .

The factory standard working u87 ai is louder airier and probably could be descibed as harsher then a u87 with the battery ..

So long story short a few years back i started to wonder about all the internet talk about the " old" ones being the great ones , i found two of exactly the same revision which without paying stupid money is really hard Then Had gunter totally rebuild them reskin recapp recalibrate They are the closest match set of u87 he has ever held . And my feeling towards them is

Meh .. I'll keep them but they are just nothing special

My faulty u87ai was so much more sensitive to everything It held a delicate magical response .

Stop paying big dollars for old u87 that arent even restored is my advice to the world There is nothing magical about them

Jeepers those grills are in good nick Rick.Did ya get him to open up the top end on them? I think they sound really good when that's done, it still has the mid thing going on but a bit more air in your hair. I know the shutdown thing you mean, guy I was apprentice to had one.Sounded great but would only shut off on the best takes.I think the other thing people might overlook is the transformer strapping and the output padding Gotham Audio had added at the factory for US orders. If an 87 has the 50 Ohm strapping and the resistors connected it's a pretty different beast.The Gotham modded ones had a red dot next to the serial number (changed to light blue in some time round the early 80's I think?)Are people paying stupid prices for the old ones? A new Ai is around 3K, I've seen a bunch of old ones around there.

I see it alot , the capsule looses just enough tension to sound incredible on soft to med things And polarises on med to loud things and shuts down for a sec The quality of the proximity effect gets more in the u47 line of things Lovely bloom , then suddenly in the middle of a vocal it cuts out Which is such a major bummer it just kills the session Lots of people are hanging on to their magic 67 or 87 despite it being frustratingly Unreliable because they are afraid a reskin will make it sound different And it will , reskin it get over it is my thought Its not THaT magical

Everytime somebody tells me they have an incredible 67 or 87 I always ask does it shut down sometimes When you dont want it to ? the answer is always yes .

Faulty , But most of us like a bit of myth n legend in our studio stuff .

I am 10 years past dealing with faulty stuff .. I just cant anymore.

a new stock capsule or mic just doesnt do that thing so yep faulty and doesnt sound as delicate . A totally spec u67 or u 87 could be descibed as robest sounding Not delicate

The u87a1 airer and louder the a u87

Fwiw i would / keep any u 87 ai i stumble across , i will sell all the old battery u87 i find From here on out .

There is a whole world of thin diaphragm capsules and magic voodo mods to get u87 to sound Magical but still be reliable but then they arent u87 they are something else / maybe better maybe worse . Ill pass and buy different mics .

You know after 30 years and hundreds of microphones either I understand exactly what a neumann microphone can do and should do or I don'tI am pretty sure I will take the bet .

I wouldnt cut a vocal without a pop shield and of coarse there are different grades of them

But nah .. Really Faulty .. Its a cancer that just gets worseIts like living in a share house with a front door lock that Has to be jiggled just "right " to get in the door every day

Your new flat mate moves in and says .."really you put up with that ? ""f@#$ it call a locksmith . "

Huge difference between servicing a microphone and using it , and thats why I service my own mics as best I can I have restored ALOT of neumanns I own ALOT of neumanns , Ii still have ALOT of not quite right ( faulty) neumanns in the drawer waiting till I can afford to fix them and I let gunter do the mission critical stuff when Ii am curious if he can do it better .

The amount of times I hear ", I sent it back to (...not rob..) he said its fine totally within spec But I got it back and it still cuts out , its really frustrating . " I speak to the tech for them who envitably said they dont want to spend the money on a capsule so I just cleaned it , and it seemed fine .

I say .. "christ spend some money on it buy a new capsule " Put the old one in a drawer . Next time I check its still the same capsule ( andy ? )

Having a faulty multi thousand dollar mic you can't trust makes none sense Spend $750 ! Some capsules just dont last 60 years some dont last 5 years.

But really .guys ... ..nah faulty .

Neumann new capsules are as good as you can hope for . They are not faulty ,theirst reskins are as good as you can hope for They are not faulty .

I do get the message rob there can be magic in the fault ! It could be design ( not)

But stuffk that ..am making records for a living not doing magic tricks .Why are old beat up u87 fetching 4k ? I have none idea ! But i am happy to tell people to buy a cmv 563 and reskin it and take your girl away with the spare change ! and some guys who mod old u87s for $2000 on top of what you paid ( kh) will tell you something different .

Rick O'NeilI think we went to different schools togetherturtlerockmastering.comwe listen

I don't know if they are getting 4k but they are listing on eBay disappearing as sold and so its looking like they are getting that.. why buy a brand new one for a thousand less when you can buy a magic beat up faulty vintage one for a thousand more ?

Hi Slavco,Something to check on a vintage u87 - inside the mic on the transformer is a sticker/label. On the label is a set of numbers reading 930-??. If the number is 930-19, 930-20, 930-21 then the u87 circuit board is optimised for frequency response, lowest self noise and highest headroom. If the number is 930-18 or lower then the circuit can be updated to achieve optimal performance. My 1977 u87 is 930-20 so no need for me to update the circuit.Gunter can do this update easily.

Also Gunter does a mod for u87ai. The mod slightly reduces the overall gain, but increases the headroom by 7dB, so after the mod it has the same headroom as the older U87. Compared to the older U87, the U87Ai has a much higher output gain, but also drastically reduced headroom, because it overloads the input of the internal amp quickly at high SPL. This is one of the reasons why most people prefer the sound of the old U87 over the U87Ai - especially for vocals when it is very easy to overload the gain stage of the U87Ai with a relatively strong voice.

Having said this, if you're intending to use a u87 for vocals or higher spl signals I'd grab an older u87 with a label that reads 930-19,20,21 for best results.

On the topic of vintage 87's all my mics had been in storage cause I took 12 months off to do some other stuff, and I started building a new room in Jan of this year. About halfway thought building the booth we had a chance to do a bit of test recording with 2 people to see how it was sounding. The guy who owns the building has a studio on the ground floor and has some modern Blue mic, the kinda one where you go "Is that a mic, or a bluetooth speaker or a sextant or something, whaaat ?" so we set them up and my 87 was waaay low and thin sounding compared to the blue. I started wondering did I drop it in the move, did something fall on it in storage? I went home depressed and spent the night waking up every hour wondering about transformer strapping, weren't the output resistors bypassed, what's going on... it sounded great before I stored it. I woke up every hour...2am - what about the transformer strapping...3am - I'm sure I bypassed the output pad...4am - jeez maybe the diaphragm took a hit....5.30am - aah ^&%$ it , I'm gonna drive in and take it apart.. at least the traffic was light.Spent an hour with a magnifying glass and a multimeter going over the whole circuit. Couldn't find a fault. Bugger it, I'll put it back together and have to send it to Ross to look at. And as I was screwing the body tube back on....I noticed the bass rolloff switch was engaged.This doesn't help with buying a vintage 87, but my wife doesn't understand so I can't tell her..

Yup... 2 main rules, never use the pad switch, never use the HPF switch...

Glad it was only that...

whats interesting about 87's, is you record on them and think, it sounds really good, but not much better than say a rode or some other cheapish mic, then you AB them and its night and day...Also they sit so well in a mix.

Rick are you sure the sound cutting out momentarily isn't something to do with moisture combining with dirt on the capsule and causing a momentary short? When Gunter fixed this problem with mine that is how he described it and a capsule clean solved the problem. He said the u87 suffers from this problem the most. When I tried to describe the problem as "whenever the singer gets close to the mic and sings loud it cuts out for a second", he instructed me to do a "breath test" and there it was...

yes yes it is of coarse that they shut down because of dirt and moisture,and moisture problems indicate its become hydroscopic i.e. its got lil cracks or holes in it .dirt can be cleaned and moisture can also just be a problem where you live .some people by the beach have a hell time with the same mic that would be a ok in the bush

but when the tension is wrong and has slipped its another problem again the capsule is to my ear much nicer and magical in the highs and the bottom bloom proximity is different

and its as sensitive as can be - you can blow it out really easily , too easily

too sensitive to be practical . I have seen it on maybe ten neuman mics out of the hundreds that have passed through my hands.

I had one with the problem that i talked about earlier loved it , but it just became impractical , they only get worse not better

my feeling is sure clean them ( i do it a lot ) but if its a regular thing that it blows out replace it and get on with important things to worry about .

this is not a just use pop filter and will fix it problem , your vintage neumann mic isn't supposed to blow out in normal regular use ( with a pop filter )
